Macromolecular, surface-active, quaternary, N-substituted chitosan derivatives as well as cosmetic composition based on these new chitosan derivatives

摘要

The cosmetic agent for the treatment of the hair and skin contains macromolecular surface-active, quaternary N-substituted chitosan derivatives having the formula (I)PPHO[C.sub.6 H.sub.11-- x--y--z NO.sub.4 (R.sup.1).sub.x (R.sup.2).sub.y (R.sup.3).sub.z ].sub.p H (1)PPwherein x is from 0.04-0.4; y is from 0.04-0.92; z is from 0.04-0.92; (x+y+z)2; p is an integer from 100-100,000; R. sup. 1 is acetyl; ##STR1## R.sup.4 is a C.sub.1 to C.sub.4 -alkyl radical; X is Cl, Br, I or CH.sub.3 SO.sub.4 ; o is 1-5; n is 5-20. The present invention also comprises chitosan derivatives having the formula (I). The chitosan derivatives are distinguished particularly by their surface- active properties, for example, their foam-forming and emulisyfing properties, and by their hair-setting and hair-conditioning effect.
